AXLE SHAFT—CARDAN U-JOINT
Single cardan U–joint components are not service-
able. If defective, they must be replaced as a unit. If
the bearings, seals, spider, or bearing caps are dam-
aged or worn, replace the complete U–joint.
REMOVAL
CAUTION: Clamp only the narrow forged portion of
the yoke in the vise. Also, to avoid distorting the
yoke, do not over tighten the vise jaws.
(1) Remove axle shaft.
(2) Remove the bearing cap retaining snap rings
(Fig. 4).
It can be helpful to saturate the bearing caps
with penetrating oil prior to removal.
(3) Locate a socket where the inside diameter is
larger in diameter than the bearing cap. Place the
socket (receiver) against the yoke and around the
perimeter of the bearing cap to be removed.
(4) Locate a socket where the outside diameter is
smaller in diameter than the bearing cap. Place the
socket (driver) against the opposite bearing cap.
(5) Position the yoke with the sockets in a vise
(Fig. 5).
